Usage

Description

Metamifop is an aryloxyphenoxypropionate (AOPP) post-emergence herbicide specifically designed for use in rice fields. It is characterized by its high control efficacy against annual grass weeds, particularly barnyardgrass, while maintaining the safety of the rice plant. The chemical properties of metamifop include its solubility in chloroform, DMSO, and methanol.

Uses

Used in Agriculture:
Metamifop is used as a herbicide for the control of annual grass weeds, such as barnyardgrass, in rice fields. Its application reason is its high control efficacy and exclusive whole plant safety to rice, ensuring effective weed management without harming the crop.
Used in Rice Farming Industry:
In the rice farming industry, metamifop is used as a selective herbicide to target and control problematic annual grass weeds. The application reason is its ability to provide effective weed control without negatively impacting the growth and health of the rice plants, leading to improved crop yields and reduced labor costs associated with manual weed removal.

Synthetic method of metamifop

The invention relates to the field of organic synthesis, in particular to a synthesis method of high-purity metamifop, the synthesis method comprises the following step: carrying out substitution reaction on fenoxaprop-p-ethyl and N-methyl o-fluoroaniline under the action of a catalyst to obtain the high-purity metamifop. The synthesis method of the metamifop provided by the invention is simple inreaction operation, a reaction system is nearly neutral, conditions are mild, and metamifop cannot be decomposed; the fenoxaprop-p-ethyl serving as the raw material is mature in production and high in purity, impurities cannot be brought into the fenoxaprop-p-ethyl by the raw material, and the prepared metamifop is high in purity and good in quality. The method is simple in process, free of threewastes, environmentally friendly, free of dangerous steps, safe, reliable and capable of achieving large-scale industrial production.
